How to Uninstall Programs Properly on Windows and Mac

Uninstalling a program should remove it completely, but many programs leave files, settings and background services behind. Removing them properly frees space, prevents conflicts and keeps startup clean. Use the built-in uninstall tools first, and check for leftovers afterwards.

Windows

Open Settings, then Apps, then Installed apps.
Find the program in the list, select the three dots, and choose Uninstall.
Follow the program's prompts. Some ask whether to keep your settings or data. Choose carefully.
Restart the computer if the uninstaller asks you to.

Mac

For most apps, open Applications in Finder and drag the app to the Trash. Some apps come with their own uninstaller, usually in the same folder or in the app's support files. Empty the Trash after removing the app.

Remove leftover files

Programs often store settings and cache files. On Mac, look in the Library folder under Application Support and Caches for folders named after the app, but delete them only after you are sure the app is gone. On Windows, check the AppData folder in your user profile with care, because it holds data for many programs.

What not to remove

Do not delete system files or folders such as Windows or System, even if they seem to belong to a program.
Do not remove drivers you need, such as printer or graphics drivers, unless you are replacing them.
Do not uninstall security software without installing a replacement.

Check startup and background items

Some programs add themselves to startup or run background services. After uninstalling, check Task Manager's Startup tab on Windows, or Login Items on Mac, and remove anything left behind.

Frequently asked questions

Why does a program still appear after uninstalling?

The uninstall may have failed partway, or a background process may still be running. Restart the computer and try again. Use the vendor's removal tool if one exists.

Is it safe to use a third-party uninstaller?

Some are reputable, but check the vendor and read reviews carefully. The built-in method is usually enough.

Check for a reinstall option

Sometimes the problem with a program is that a file is damaged, not that the program is wrong. Many installers offer a repair option that fixes the program without losing your settings. Try repair first if the program crashes or behaves oddly, and uninstall only if repair does not help.

Back up settings before you remove an app

Some programs store licence keys, custom settings or saved projects in the app folder or the user profile. Before you uninstall, export the settings or copy the data folder to a safe place. This is especially important for editing tools, games with saves and software with activation codes.
